If given the mole fraction of water in an aqueous sucrose (C12H22O11) solution and asked to calculate the molality of the soluti
olasank [31]

Answer:

No additional information is required in order to calculate the molality of the solution.

Explanation:

Mole fraction of water = \chi_1

Mole fraction of sucrose = \chi_2

\chi_1+\chi_2=1

From the given mole fraction of water mole fraction of sucrose can be determined.

And from both values of mole fraction moles of water and sucrose can also be calculated.

\chi_1=\frac{n_1}{n_1+n_2}

\chi_2=\frac{n_2}{n_1+n_2}

After calculating the moles of water convert them into mass of water in grams and then change that into kilograms say that be M'.

Finally we can determine the molality of solution ;

Molality=\frac{\text{Moles of compound}}{\text{mass of solvent (kg)}}

Molality of the sucrose solution ;

m=\frac{n_1}{M'}

From this we can conclude that no additional information is required in order to calculate the molality of the solution.

What is responsible for the unusual ecosystem of the Ethiopian Highlands? (Select all that apply.)
Phantasy [73]

The Highlands consist of constantly erupting volcanoes.

The Highlands formed by uplifting volcanic activity.

<h3> Erupting volcanoes</h3>

The Highlands consist of constantly erupting volcanoes and the lands formed by uplifting of regions due to volcanic activity are the factors that are responsible for the unusual ecosystem of the Ethiopian Highlands.

<h3>Causes of unusual ecosystem</h3>

There are eight types of ecosystem are present in Ethiopia. All these ecosystems are formed due to Volcanoes and volcanic activity which make the unusual ecosystems in the highlands of Ethiopia so we can conclude that volcanoes and volcanic activity is responsible for unusual ecosystems in Ethiopia.
